Hi, I'm getting this error when sending message (responding to user on the mailing list). Does someone has a small idea where I could start my investigation ? I'm hosting my mail server on Cloudflare DNS but the MX record is in clear. The mail server is using a reserved IP and it is serving many domain name for email. I was thinking that maybe I should start thinking about hosting my own email server. But I wasn't sure if I felt like I had the nerve to do so. Some people say it's a lot of maintenance work. I don't want to use Google for my domain as a email provider, this is too costly. The actual hosting provider I use (Namecheap) does a great job, except that because it's a shared hosting provider my mail often gets flagged junk and seem to always raise some problem with DMARC compliance, possibly relating to the above. Thanks, Start of the error message received by "returned mail" : Reporting-MTA: dns; premium58.web-hosting.com Action: failed Final-Recipient: rfc822;bjoern.ricks@greenbone.net Status: 5.0.0 Remote-MTA: dns; mail.greenbone.net Diagnostic-Code: smtp; 550 X-Host-Lookup-Failed: Reverse DNS lookup failed for 162.213.253.79 (failed) -- Polyna-Maude R.-Summerside -Be smart, Be wise, Support opensource development
